TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 451,082, dated April 28, 1891.

Application filed April 15, 1889.

To all whom, t may concern:

Be it known that I, DAVID HADDIX TAY- LOR, of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Type-Iriting` Machines, of which thefollowing is a specification, reference being had to the annexed drawings, forming a part thereof, in which- Figure l is a side sectional elevation of a portion of a type-writer embodying my invention. Fig. 2 is a side elevation of the type-shifting mechanism. Fig. 3 is a perspective view of the beveled finger-key. Figs. 4 and 5 are respectively front and rear views of a modified form of type-arm, and Figs. 6 and 7 are respectively side and plan views of the same.

Similar letters of reference indicate corresponding parts in all the views.

The object of my invention is to construct a type-writenin which capitals or lower-case may be written by a single set of keys, so that the use of a capitalizing-key will be avoided.

The invention consists in the construction .and combination of parts hereinafter dcscribed and claimed. l t

As the construction of all the type-arms and the parts connected therewith is the same, I show and describe only a single type-arm and the mechanism by which it is operated.

The ring A, which supports all of the typearms B, rests upon columns projecting from the base C. The type-arm B is pivoted in the loop a, attached to the ring A, and to the free end of the said type-arm is pivoted a type-lever D, carrying the lower-case type b and the upper-case type c. To the ring A, at the side of the loop o., is secured atriangular loop E, to the upper and outer corner of which is pivoted a link F, and to the center of the link F is pivoted another link d, and the said link CZ is connected with the lower end of theV type-lever D by the wire e. The type-arm B is extended laterally near its pivotal point and curved backward toward the ring` A, and to this portion of the arm is pivoted the wire f,- which is pivotally connected with the key-lever G in the usual way, so that whenever the key-lever G is depressed Serial No. 307,278. (No model.)

in the manner presently to be described the type-arm B will be thrown up into the position shown in dotted lines.

To the lower end of the link F is pivoted a wire g, which is pivotally connected with the key-lever H. In the present case the keyle-vers are in different planes for the sake of clearness in thedrawings; but in actual practice they are arranged side by side. The keylevers G H are pivoted to a fixed support, h at the front of the machine, and are guided by the slotted posts t' at the rear of the machine. A cross-bar j extends over the key-levers GI-I, and is perforated to receive the rods 7a l, which are attached, respectively, to the keylevers G I-I. The said rods 7c Z are pivotally connected to the key-levers G I-I.

To the upper end of the rod 7c is attached a finger-piece m, which hasa rabbet in its rear edge for receiving the finger-piece n, the said finger-piece n being provided with a neck o, which extends down through a slot p in the rabbeted portion of the finger-piece nu The key-levers G H are returned to their normal position by the at springs q o", which extend underneath the said levers and tend to press them upward. When the fingerpiece fm is depressed, the key-lever G descends andthe arm B is made to turn upon its pivot, carrying the lower-case type upward into contact with the ink-ribbon, producing the impression of the lower-case letter on the paper, the parts at the moment of printingbeing in thelposition shown 'in dot-ted lines in Fig. l. When the finger-piece 'n is depressed by virtue of its engagement with the finger-piece m, both of the said fingerpieces are carried downward, moving the levers G H downwardly, thus causing the typearrn B to rise, as before; but the downward pull of the key-lever H turns the link F on its pivot, so as to draw back the link d, and thus through the medium of the wire c turn the type-lever D on its pivot, so as to bring the upper-case type c into position for printing. Vhen the finger is removed from the finger-piece n, the parts return to their normal position, and the type-lever D is in position for writing the lower-oase. It will thus be seen that when it is desired to write only lower-case the finger-piece 'm will be de- IOO pressed; but when it is desired to write capitals both finger-pieces m n will be depressed. It Will be seen that the parts m n form a double or two-part finger-piece or key, the parts of which interlock for separate or simultan eous movement.

For convenience :in labeling the keys-a depression is made in the uppersurface of the part m, as shown in Fig. 3. Into this recess is inserted a disk of porcelain, glass, or other suitable material, upon which is marked the appropriate letter.

Then it is desirable to make the type-writer very compact, the arm B will be made hollow and the triangular loop E will be arranged opposite the center of the said arm. In this case the arm B will be operated by a forked rod connected with the key.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. The combination, with a type-arm .provided with apivoted type-lever carrying npper and lower case type, of key-levers conneet-ed with said type-arm and lever, respectively, and a two-part inger-piece or key, the parts of which are separately connected for simultaneous or independent movcment,sub stantially as set forth.

2. The combination, with the type-arm B, of the type-lever D, carrying upper an d lower terlock for simultaneous or separate movement, and connections between said parts and the type-arm and type-lever, respectively, substantially as set forth.

4. In a type-writing` machine, the combina-4 tion of the key-levers G Il, the linger-pieces m n, adapted to operate the key-levers, the type-arm B, the type-lever D, carried by the said type-arm and provided with two characters, the triangular loop E, the links F d, and the connecting-wires e f g, substantially as specied.

5. In a type-writer, a two-part key formed of the finger-piece m, having a transverse rabbet across its inner end and a vertical slot 2J intersectingI the same, and the finger-piece n, resting;` on the rabbeted end of the piece m and having' a neck o extending down through-the said slot, substantially as set forth.
